Bentley Seequent PLAXIS Monopile Designer 2025.1.3.5: Offshore Wind Foundation Engineering Software

PLAXIS Monopile Designer 2025.1.3.5 is a specialized finite element software package engineered for the analysis and design of monopiles used as foundation elements for offshore wind turbines, specifically under lateral loading conditions .

This software transforms the findings of the PISA (Offshore Wind Joint Industry Research Project) into daily engineering practice . While it functions as a stand-alone tool for rule-based design, its full potential is unlocked when integrated with PLAXIS 3D, allowing for advanced numerical calibration of soil reaction curves derived from 3D FEM models .

The 2025 version continues to refine the enhanced design method based on PISA Phase 2, enabling precise 1D analysis of large-diameter monopiles in complex layered soils. Ultimately, this methodology empowers engineers to reduce the embedded pile length by up to 35%, resulting in substantial savings in steel, fabrication, and transportation costs
